Ptychophylloceras sp. Fossil Ammonite – Callovian, Jurassic – Tulear, Madagascar

About the Fossil:

This beautifully preserved Ptychophylloceras sp. ammonite fossil originates from the Callovian stage of the Middle Jurassic (~166-163 million years ago) and was discovered in Tulear, Madagascar. Ptychophylloceras is a genus of phylloceratid ammonites, known for their smooth, involute shells with complex suture patterns and highly distinctive morphology, making them an intriguing species in the ammonite fossil record.

During the Middle Jurassic, ammonites like Ptychophylloceras sp. inhabited warm marine environments, where they played an essential role in ancient marine ecosystems. Unlike other ammonites, phylloceratids such as Ptychophylloceras are believed to have been deep-water species, with their streamlined shell structure suggesting enhanced swimming capabilities. The Callovian deposits of Tulear, Madagascar, are well-known for their ammonite-rich formations, providing valuable paleontological insights into the evolution of Jurassic cephalopods.

Jurassic Information

The Jurassic Period (201–145 million years ago) was the golden age of dinosaurs, with iconic species like Brachiosaurus, Stegosaurus, and Allosaurus dominating the land. It was a time of warm, humid climates, with high sea levels that created vast shallow seas, supporting abundant marine reptiles, ammonites, and early coral reefs. The first birds, such as Archaeopteryx, evolved from small theropod dinosaurs, while early mammals remained small and nocturnal. Lush forests of cycads, conifers, and ferns covered the land, providing food for giant herbivores. The breakup of the supercontinent Pangaea accelerated, shaping Earth's geography and setting the stage for the diverse ecosystems of the Cretaceous.
